Answer to Question 1

C

Answer to Question 2

Defining the systems of speech is only a convenience, because none of the four systems operate in isolation. To produce the sounds of speech, all of the systems of speech must operate together in a highly integrated manner. The science of speech is extremely complicated, and defining the systems of speech simply makes it easier to discuss normal speech production and speech pathology.
